The formula for distance between two points is:
In this case:
![x_{2} =0\\x_{1} =3\\y_{2} =-9\\y_{1} =-8](https://tex.z-dn.net/?f=x_%7B2%7D%20%3D0%5C%5Cx_%7B1%7D%20%3D3%5C%5Cy_%7B2%7D%20%3D-9%5C%5Cy_%7B1%7D%20%3D-8)
^^^Plug these numbers into the formula for distance like so...
![\sqrt{(0-3)^{2} + (-9 - (-8))^{2}}](https://tex.z-dn.net/?f=%5Csqrt%7B%280-3%29%5E%7B2%7D%20%2B%20%28-9%20-%20%28-8%29%29%5E%7B2%7D%7D)
To solve this you must use the rules of PEMDAS (Parentheses, Exponent, Multiplication, Division, Addition, Subtraction)
First we have parentheses. Remember that when solving you must go from left to right
0 - 3 = -3
-9 - (-8) = -1
![\sqrt{(-3)^{2} + (-1)^{2}}](https://tex.z-dn.net/?f=%5Csqrt%7B%28-3%29%5E%7B2%7D%20%2B%20%28-1%29%5E%7B2%7D%7D)
Next solve the exponent. Again, you must do this from left to right
(-3)² = 9
(-1)² = 1
![\sqrt{(9+1)}](https://tex.z-dn.net/?f=%5Csqrt%7B%289%2B1%29%7D)
Now for the addition
9 + 1 = 10
√10 <<<This can not be further simplified so this is your exact answer
Your approximate answer would be about 3.16
***Remember that the above answers are in terms of units
Hope this helped!

It is 2.1 inches longer. Plz plz plz give me brainiest answer I only need 3 more to rank up. If u do I will show my work and show the answer as a fraction.
So for the two equations: Not sure how hard you want them but....
15+1=16 and 13+ 18=21
For the open equation.
2x + x(5+7)=105
=22.3
hope this helps you(:
if not plz let me know
have a good day
